摘要

Process for treating silicate raw material to produce natural sorbent or made of litter for cats and small animals Silicate raw materials from the group kaolin, clays, zeolite, bentonite, quartz sand, feldspar, limestone, dolomite, diatomaceous earth, sepiolite, expanded perlite or vermiculite, muscovite, biotite, expanded cypris clay and expanded calcined kaolin or mixtures, optionally to increase the whiteness, brightness and colour change of the dry bed, they are subjected to the effects of high intensity or superconducting magnetic separation of a magnetic field with a magnitude of magnetic induction of up to 5 T, possibly up to 10 T and/or in a spray drier together with the reducing effect of decomposition products and the physical attraction of a thin film layer of white bentonic on the surface of the natural sorbent.
